1. Discussion 2.1Nuclear Energy and otherenergy sources2.1.1 Nuclear Energy versus Fossil Fuel Energy Whenthe comparison between nuclear and fossil fuel power plants find out they havesame working principle which state convert potential thermal energy intomechanical rotation with difference type of used fuel that generate heat toproduce steam that drive Steam Generator to afford electricity.
Every day the worldoil reserves shrink and in future will be unavailable. The thermal energy suppliesin fossil fuel plants come from burned oil, natural gas, coal to obtainnecessary thermal energy. The fundamental difference between the nuclearand fossil fuel station in terms of financial cost is running and maintenancecosts.
The running cost in fossil fuel station is higher than nuclear station.In order to be produced 1(GW) coal-fired power plant is needed 9000 TON of fuelper day while a nuclear plant consumes about 3(kg)of uranium in the same production and time. The waste burned fossil fuel constitutethe largest danger facing humanity after combustion fossil fuel yields CO2″carboxyl” which is one of the causes ofglobal warming. In addition combustion remnants have negative effects on theenvironment such as (methane, Sulphur dioxide,nitrous oxides, and other pollutants). The nuclear power plant is considered to be somewhat eco-friendly interms of there are not gaseous emissions. 2.1.2 Nuclear Energy versus Hydroelectric Energy The hydroelectric energy is very effective,economic, clean no gaseous emission.
This technology utilize in areas rich inriver water by take advantages flow rate of rivers they are stored in huge damsand then avail the sum of energies for river (kinetic energy, potential energy,and internal energy ) so as to rotateturbines to generate electricity. + z1 + + Hp – HT – Hloss= + z2 + Bernoulli’s equationexpress all sum of kineticenergy, potential energy, and internal energy must be constant at same along astreamline. Implying with increase fluid speed will be caused increasing inboth dynamic pressure and kinetic energy occur when the sum of energies are reducedat simultaneous. Although the hydroelectric stations haveadvantages but also it adversely impact on the surrounding environment themajor problem oppose this technology the nature of the river is unstableimplying there are dry seasons that maycause the station is stopped or operate with low efficiency.
In addition, thehydroelectric stations have certain risks related by construction and operationincluding foundation problems andenvironmental damage for areas flooded and downstream. 2.1.3 Nuclear Energy versusWind Energy Wind turbine isone of the common renewable energy, the wind energy is modern technology it canbe high efficiently, which provide energy from natural sources, withoutenvironmental impact.
It does not causes greenhouse gases. At it’s operate on asimple principle. The energy in the wind turns two or three turbine’s blades arounda rotor. The rotor is connected to the main shaft (drive shaft), which spin adrive shaft connected to a gearbox with driven shaft to increase the rotationof generator that makes electricity large.
Simply, a wind turbine works theopposite of a fan. It has an instrument on the top of the nacelle, ananemometer and a wind vane, which measure wind speed and direction. When thewind changes direction, motors turn the nacelle, and the blades along with it,around to focus into the wind to ensure that the optimum amount of power isextracted from the wind, this means that the wind is not constant, therefore,it don’t produce the same amount of electricity all the time. In addition, its noisyWind turbines, can convert the kinetic energy in the wind into mechanicalpower. This mechanical power can converted into electrical energy usinggenerator to produce electricity. Turbines are grouped together to form ofa wind power plant, where as large spaces of land use.
